| 2020-02-27 | NFC: Replace zero-length array with flexible-array member | Gustavo A. R. Silva | 1 | -1/+1 | |
| The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

| 2018-06-12 | treewide: devm_kmalloc() -> devm_kmalloc_array() | Kees Cook | 1 | -2/+2 | |
| The devm_kmalloc() function has a 2-factor argument form, devm_kmalloc_array(). This patch replaces cases of: devm_kmalloc(handle, a * b, gfp) with: devm_kmalloc_array(handle, a * b, gfp) as well as handling cases of: devm_kmalloc(handle, a * b * c, gfp) with: devm_kmalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kmalloc_array(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kmalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kmalloc..." instead of "= devm_kmalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kmalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kmalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;

| Joe and Bjørn suggested that it'd be nicer to not have the cast in the fairly common case of doing *(u8 *)skb_put(skb, 1) = c; Add skb_put_u8() for this case, and use it across the code, using the following spatch: @@ expression SKB, C, S; typedef u8; identifier fn = {skb_put}; fresh identifier fn2 = fn ## "_u8"; @@ - *(u8 *)fn(SKB, S) = C; + fn2(SKB, C); Note that due to the "S", the spatch isn't perfect, it should have checked that S is 1, but there's also places that use a sizeof expression like sizeof(var) or sizeof(u8) etc. Turns out that nobody ever did something like *(u8 *)skb_put(skb, 2) = c; which would be wrong anyway since the second byte wouldn't be initialized.
